oIL-BURfime APPARATUS Application filed July 21, 1928. Serial .No.294,391.

v My invention relates to oil burning apparatus, of the type in whichoil is supplied to a burner-head for combustion. I

The object of my invention is to provide a burner-head of simpleandzcheap construction in which the oil and air may be supplied withoutany danger of forcing any oil from the burner-head chamber by airflowing therein under pressure.

A further object is to provide means for preventing carbon from beingdeposited on the upper side of the cap of the burner-head.

Referring to the drawings which form a part of this specification,

Fig. 1 is a plan view of a burner-head em.- bodying my invention. 1

Fig. 2 isan elevational side sectional view of the burner-head. I

Fig. 3 is a fragmental sectional view of a portion of the burner-head,shown on an enlarged scale. I

A, indicates a central cylindrical casting or. sheet metal conduit forair, which also serves to support an annular basin B, which may be 5made of cast iron, and slipped upward over the hylinder A, before thejoint A, is made with the laterally extending portion A of the conduit,for air.

An oil-tight joint 0, is made between the inner edge of the basin B, andthe wall of the conduit with the top of conduit located on a horizontalline withthe top edge of the basin, as shown.

A V shaped recess D, is formed in the bottom of the basin between theouter' wall of the conduit and the inner bottom end portion of thebasin, and a circular porous wick E, of heat refractory material, restsin said recess. and'is rovided with a conically shaped lower sur ace Ewhich abuts the inclined surface E formed on the inner side of the basinas shown. The basin B, is formed with a, boss F, having a passageF'leading to the wick E, and a pipeH, leading to the passage to conductoil to the wick.

The basin is formed with a shallow annular depression G, which serves tohold. any oil which overflows from the wick, the lowest portion of saiddepression being located directly under the outer'edge I of the cap I,

the deflecting ring which edge is positioned approximately mid-' waybetween the upper end of the conduit A, and the outer rim B,-pf-theichamber B.

Just below the top end A of the conduitA, a circular outwardly extendinflange A is. formed integral with'th'e conduit, a'nd'a circu; lar airdeflecting ring J, is supported thereo in removable'relation therewith.

- A three legged bracket K, shaped as shown, rests on the top edge ofthe conduit A, in freelyremovable relation thereto, and is provided witha boss K, having a threaded hole K extending therethru. 'A threaded rodL, extends thru said boss and supports the cap I, and an inner shield M,spaced apart from each other by the washer N, and are held together bythe two nuts OO respectively.

The cap and shield are semi-spherical in form, as shown.

The cap and shield areadjustable relative to the basin B, as will bereadily understood.

The wick E, may be made in two; or more portions so that a new wick maybe inserted without difliculty.

The device operates as follows:

Oil is maintained on a level with the upper side of the wick E, bysupply means not shown herein. I

Air under pressure flows thru the conduit A, between the legs of thebracket K. and is deflected downwardl by the shield M, over J into thebottom G, of the basin B, and mixes with thepil vapor generated by heheat reflected from the burning fuel in the fire box and upper side ofthe basin, in which, the burner-head is located in the usual position.

The space between the cap Land shield M,

serves to .prevent chilling of the cap, which would cause oil vapor tocondense on the upper side thereof, and earbonize.

The air being deflected downwardly and outwardly, strikes the lower partof the basin at the outer rim of the depression formed therein, and doesnot lift the oil bodily therefrom, but mixes with the oil and vaporwhich flow, together from the basin and burn freely im the combustionchamber. f

This arrangement of the burner parts,- overcomes the trouble caused byair hfting the oil bodily from the bottom of the basin, which was one ofthe defects of my earlier burner-head.

The parts of the burner-head are so assembled, that they may be easilydisassembled for cleaning or repairs, as will be clearly understood fromthe drawings.

Having thus described my invention, I

claim as new:

1. A burner-head of the character described comprising a conduit forair, a basin supported by said conduit, a wick in said basin, means forleading oil to said wick, a cap supported above the upper end of saidconduit adapted to deflect air into said basin, and a ring fordeflecting air mounted on said conduit below said cap.

2. A burner-head of the character described comprising a conduit forair. a basin supported by said conduit, a wick in said basin, said basinhaving a passage for oil leading to said wick; a cap and a shield spacedtherefrom, supported above the upper end of said conduit and adapted todeflect air into said basin.

3. A burner-head of the character described comprising a cylindricalconduit for air, an annular basin supported thereby, a wick in saidbasin, means for leading oil to said wick, a cap and shield open .to theatmosphere at their undersides and held together in spaced relation andsupported above the upper end of said conduit and adapted to deflect airinto said basin.

4. A burner-head of the character described comprising a circularconduit for air, an annular basin mounted thereon having a passage foroil formed therein, and a V-sh'aped recess formed in the bottom thereof,

a wick in said recess iii open communication with said passage for oil,a dome shaped cap open at its under side to the atmosphere and supportedby said conduit above the upper end thereof the rim of which ispositioned above the middle of the basin.

5. As stated in claim 1, together with a ring mounted on the conduit fordeflecting air to the middle of the basin.

6. As stated in claim 4, together with a dome shaped shield open to theatmosphere on its under side and held in spaced relation with the cap.

7. As stated in claim 3; said shield and cap being freely removable fromsaid conduit and adjustable relative thereto.

In testimony whereof I have affixed my signature.

ALBERT- E. GRANT.
